+Nomenclature for a new issue
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+In |main_project_name|, for the opening of a new `Issue::Bug` the team decided to adopt 
+a common nomenclature to apply to the title of each new issue. 
+Depending on the scope to which the issue refers, three options are defined.
+
+Option 1 - Board-related
+------------------------
+
+When the issue is opened related to a specific board, the parameters to be given 
+are: **Domain** and **Board**.
+
+| [MAINTENANCE][$BOARD] - $Title
+| [NETWORK][$BOARD] - $Title
+| [OpenHarmony][$BOARD] - $Title
+| [OTA][$BOARD] - $Title
+| [SECURITY][$BOARD] - $Title
+| [PERFORMANCE][$BOARD] - $Title
+| [HW][$BOARD] - $Title
+| [TOOLCHAIN][$BOARD] - $Title
+| [MISC][$BOARD] - $Title
+
+*Example:*
+    
+[Maintenance][BOARD X] - Build failed due to ModemManager error
+
+Option 2 - Blueprint related
+----------------------------
+
+When the issue is opened related to a specific blueprint, the parameters to be given 
+are: **Blueprint** and **Domain**; if necessary even **Board** (when Blueprint has 
+more than one board in the configuration. To be omitted if there is only one board).
+
+| [$BP - MAINTENANCE][$BOARD] - $Title
+| [$BP - NETWORK][$BOARD] - $Title
+| [$BP - OpenHarmony][$BOARD] - $Title
+| [$BP - OTA][$BOARD] - $Title
+| [$BP - SECURITY][$BOARD] - $Title
+| [$BP - PERFORMANCE][$BOARD] - $Title
+| [$BP - HW][$BOARD] - $Title
+| [$BP - TOOLCHAIN][$BOARD] - $Title
+| [$BP - MISC][$BOARD] - $Title
+
+*Examples:*
+    
+| [CATS - HW] - Black screen when flashing the image
+| [ENERGY GATEWAY - OTA][Raspberry Pi 4B] - Can't upload the image via OTA
+
+Option 3 - Domain related
+-------------------------
+
+When the issue isn't related to a specific blueprint or board, the parameters 
+to be given is **Domain**.
+
+| [MAINTENANCE] - $Title
+| [NETWORK] - $Title
+| [OpenHarmony] - $Title
+| [OTA] - $Title
+| [SECURITY] - $Title
+| [PERFORMANCE] - $Title
+| [HW] - $Title
+| [TOOLCHAIN] - $Title
+| [MISC] - $Title
